CO(2) capture and storage (CCS) has the potential to develop into an important tool to address climate change. Given society's present reliance on fossil fuels, widespread adoption of CCS appears indispensable for meeting stringent climate targets. We argue that for conventional CCS to become a successful climate mitigation technology--which by necessity has to operate on a large scale--it may need to be complemented with air capture, removing CO(2) directly from the atmosphere. Air capture of CO(2) could act as insurance against CO(2) leaking from storage and furthermore may provide an option for dealing with emissions from mobile dispersed sources such as automobiles and airplanes.
CO2 捕集与封存（CCS）有可能发展成为应对气候变化的重要工具。鉴于当前社会对化石燃料的依赖，如果要想严格地实现气候目标，CCS 的广泛应用似乎不可或缺。我们认为，传统的 CCS 要想成为一种成功的气候缓解技术——这就必须大规模运作——就可能需要辅以从大气中直接捕集 CO2 的空气捕集技术。CO2 的空气捕集可以作为防止 CO2 从封存中泄漏的保险措施，而且还可能为处理汽车和飞机等移动分散源的排放提供一种选择。
